FLANGE FOR DEATHS, VENTS, AND OTHER PURPOSES.

Specification of Letters Patent.

Patented Aug. 1'7, 1915 Application filed November 5, 1914. Serial No. 870,538.

- To all whom it may concern:

Be it known that I, JAMES R. Sarrrn, a citizen of the United States, residing at Mechanicsville, county of Saratog'a, and State of New York, have invented certain new and useful Improvements in Flanges for Drains, Vents, and other Purposes, of which the following is a specification.

This invention relates to roof flanges for drains, vents and other purposes.

My object is to provide a roof flange which will be adapted for use in connection with either a wooden or a concrete roof and will embody improvements whereby the joint between the conductor or pipe and the flange and 'roof will be water-tight, secure and rigid, and easily installed, repaired or removed.

The invention is adapted for use in connection with any pipe or conductor on either a concrete or a wooden roof and in connection with a drain pipe or vent p pe, and whether or not a cap be used, while being adapted for the removal of the cap if one is employed.

I am aware that the invention is susceptible of modification within the spirit and scope thereof, but in the following descrip tion have set forth one embodiment thereof and illustrated the manner in which the flange is connected to both a Wooden and a concrete roof.

The novel features and points of the invention are recited in the appended claims.

In the accompanying drawings: Figure 1 is a vertical section showing the invention applied to a concrete roof; and Fig. 2, a similar view showing it in position on a wooden -roof.

Referring first to Fig. l, the concrete roof appears at l and the wooden form for constructing the roof at 2. The flange proper is made as a single, integral casting having the cup 3 provided with opening 4 in its bottom, and the annular concentric flanges 5 and 6 having the base 7 and out-standing flange 8. The flanges 5 and 6 define an open topped annular channel which surrounds the upper part of the cup 3. The flange 8 is embedded in the concrete 1, while the flange or wall 6 constitutes the inner abutment or boundary for the concrete 1, and the bottom 7 rests upon the concrete roof 1. Preferably, the interior of the cup 3 tapers from its upper margin 9 to its bottom 10 so that the jute packing 11 and the calking lead or material 12'may be tightly driven or tamped into the cup and around the pipe or conductor 13. The opening 4 is circular and the bottom 10 of the cup snugly receives the pipe or conductor 13 so that when the jute 11 and oalking lead 12 are packed or tamped down, a water-tight and rigid joint is formed between the cup and the pipe.

The felt or slag roofing 14 which lies on the upper surface of the concrete roof 1 is brought down into the annular pit or well and against the flange or wall, as shown at 15, and lies on the bottom 7, within said pit or well, as at 16, the parts 15 and 16 extending all the way around the pit or well so as to pack every part of the joint. An annular spring locking ring 17 lies in the well or pit and expands against the part connecting the parts 15 and 16' so as to hold the slag or felt roofing 14 against the wall 6 and bottom 7. The ring 17 may be of any preferred form suchas a split expansion ring. Thereafter tar 18 is run into the well or pit on top of and against the felt or slag roofing 14, thus completely sealing the joint between the flange 6 and the roof. I Wish it understood that when I refer to a felt or slag roofing 14, I have also reference to any material which may be superposed on the roof 1 and brought down into the well or pit for the purpose of sealing the joint. Further-- more, when I refer to tar 18, I also am understood as including any packing or filling, preferably one of a plastic nature which will harden on cooling, that may be used for this purpose.

If the flange is employed at the upper end of a drain pipe or conductor 13, a dome shaped perforated cap 19 may be provided, which will have lugs or ears 20 to fit'in the upper part of the cup 3 above the calking lead 12 so as to be readily placed in position or removed and for the purpose of exclud ing foreign matter. If, however, the invention is used in connection with a vent pipe, as shown by dotted lines 21, Fig. 1, the cap 19 will be dispensed with, as vent pipes run up above the roofing.

Referring to Fig. 2, I have there shown the invention as applied to a wooden roof 22. With such a roof, it is unnecessary for the roof to extend up against the side of the cup 3. The flange 8 in this form of the invention, instead of being provided as an extension in the same general plane as the bottom 7, is used as a supporting flange 8 at the upper end of the wall 6 and rests upon and is preferably sunk flush with the top of the roof 22. Otherwise the construction is as previously described and in this form of the invention, the pipe or conductor 13 may be a drain or be extendedabove the roof as a vent pipe, as shownby dotted lines 21, Fig. 1. In both forms of the invention, the flanges 8, '8 serve as a support for the casting, the flange 8 being embedded in the concrete in Fig. 1, but it will be understood that the said flange 8 could be provided at the top of the flange or wall 6 in connection with a concrete roof.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a roof flange for pipes or conductors, a centrally disposed cup adapted to receive the pipe or conductor, a bottom wall outstanding from, and joined to the cup, a side wall joined to the bottom wall and ar ranged concentric to the cup and defining, in connection therewith, an annular Well or pit for the reception of packing for the oint between the roof flange and the roof, and a flange projecting outwardly from the side wall and adapted for supporting the entire device from the roof.

2. The combination with a roof, of a centrally disposed cup, a pipe or conductor received in said cup, packing contained within the cup and adapted for packing the joint between the pipe and cup, a bottom wall outstanding from, and joined to, the cup, a

side wall joined to the bottom wall and arranged concentric to the cup and defining, in connection therewith, an annular well or pit, a flange projecting outwardly from the side wall and engaged with the roof for supporting the device therefrom, a roof covering received in the well or pit, and a pack ing in said well or pit which packs the joint of the roof covering therewith.

3. The combination with a roof, of a centrally disposed cup, a pipe or conductor received in said cup, packing contained within the cup and adapted for packing the joint between the pipe and cup, a bottom wall outstanding from, and joined to, the cup, a side wall joined to the bottom wall and arranged concentric to the cup and defining, in connection therewith, an annular well or pit, a flange projecting outwardly from the side Wall and engaged with the rooffor supporting the device therefrom, a roof covering received in the well or pit and lying against the side and bottom wall aforesaid, a holding or securing ring contained within the well or pit for pressing the roof cover.- ing against the bottom and side Walls aforesaid, and a packing in said well or pit which packs the joint of the roof covering therewith.

In testimony whereof, I hereunto aiiix my signature in presence of two witnesses.

JAMES R. SMITH.
